The operation principle of SB200 is based on the screw self-locking gear. The engine is mounted on the platform itself and rotates a threaded nut, which moves along the stationary screw, this way lifting the platform. The shaft is constructed on the basis of an anodized aluminium frame interconnected with the panels of a client’s choice. Multi-layered sandwich panels and laminated glass panels come as a standard. A maximum of three doors may be installed on each floor with either left or right swing. The doors on the top floor stop may be designed in the form of gates. This type of construction looks aesthetic and modern and gives a clear view of the surroundings. At the request of the client, the platform and panels may be painted in any RAL scale colour. SB200 is a standard colour RAL9006 (white aluminium).
SB200 is designed for a comfortable use by all categories of passengers, including the elderly and people with limited mobility. Our platform lift fits perfectly both in the interior of buildings, and in a variety of external architectural styles even, in some cases, improving the aesthetics of buildings. In the case of internal installation, SB200 has all the essential qualities of a platform lift: minimum overall dimensions, no pit and machine room, silent operation and low energy consumption. SB200 may be installed in libraries, museums, hospitals, schools, airports, railway stations, aboveground and underground passages or parking. Our lifts are widely used in private houses, cottages and apartment buildings. SB200 is durable and unpretentious in service, adaptable to different standards of power sources and can withstand large power surges.
The absence of the lift cabin in SB200 lets us make a spacious and light platform. A standard platform (1,485 x 1,070 mm) ensures a comfortable journey for a person with a wheelchair and his attendant. The control of the platform is very simple and intuitive, with a stable system to incorrect commands or its consequences. A passenger may stop and resume the movement at any time of the trip and even change the lift’s moving direction. The beginning and the ending of the lifting process are performed in very smooth easing algorithms and don’t evoke any uncomfortable feelings for sensitive people. A uniformly backlit control panel, with a comfortable handle below, contains large buttons with embossed symbols at a convenient height for access from sitting or standing positions.
We use the latest LED technology for the lighting of SB200 as it is cost-effective, durable and has a wide palette range. The sets of a large number of LED elements provide uniform illumination and an excellent aesthetic appearance. Energy saving LED lighting may stay on for a long time even in case of an emergency power failure. A backup battery installed on the platform may keep the necessary level of lighting for a couple of hours.
Anti-slip floor surface
The platform floor cover is made of rough anti-skid material, which is highly adhesive and abrasion resistant. The floor coating material may contain logos, promotional materials or pictures according to our clients’ needs.
The vertical platform lift SB200 combines time-tested design solutions and new approaches to electronic control and fault diagnosis. By using the highest quality materials and components, our task is to increase the longevity of the lift and to minimize the downtime associated with troubleshooting and maintenance. The elevator control system can be equipped with a special diagnostic module that provides the detailed information on the status of all platform nodes and system sensors. The module informs about the usage of SB200, including the number of lifts and trip distances. It also enables the performing and adjustments of the lift operating settings, including speed and smoothness, the height of stops, lock closing time, button modes and much more.
With the sufficient expertise of staff a computer may be used instead of a module to implement the modifications and even reprogram the system completely.
The maximum efficiency of SB200 is achieved by using lighter materials, power saving lighting technologies and selecting a specific electric drive. The electric drive of the lift is constructed on the basis of an electronic frequency converter, which has the best characteristics of power consumption compared to directly connected motors, and enables the adjustment of the speed and smoothness of movement. SB200 lifts come with either a three-phase or single-phase frequency converter, depending on the capabilities of the present electrical circuit and intensiveness of lift usage. The frequency converter always provides the engine with the most optimal energy supply and prevents any energy wastage at the same time adapting to the grid voltage drops.
Barduva is continuously improving its vertical screw driven platform in terms of security and reliability indexes. The product reliability is the feature which is beneficial to both consumers and manufacturers. Long-term testing has shown that even after 50,000 cycles and more than 600,000 meters of travel the amortization of the main gear was hardly recognizable. The control system of SB200 lift has passed stringent tests on the impact of the strong external electrical interference and received a certificate of electromagnetic compatibility (EMC). Technical maintenance service performed a general analysis on the lift design and its schematic solutions, in order to identify any possible weaknesses in security, and came to the conclusion that all measures are fully implemented, confirming the certificate of conformity. The security measures implemented in the SB200, comply with one of the most stringent European standard EN81-41: 2010. SB-200 always stops at an exact indicated position thanks to the triple braking torque system:
• Self-braking torque of a nut and a screw
• Electromechanical brake inside the motor
• Electromechanical brake on the nut, executed by powerful solenoids
• In case of emergency situations the lift mechanism is supplied with a manual emergency descent. Optionally, the emergency lowering mechanism may be actuated by an electric motor with a backup battery.
